本文采用多重尺度法分析了具有缓慢调制的波列在多孔海床上的演化问题.海床上部波浪采用了势流理论,海床下部的渗流采用了Darcy定律.两者在海床面上进行衔接,从而导出了上部波浪的波幅一阶和二阶的调制方程,并求出了相应的解,下部渗压场的解亦同时给出. 相似文献

In this paper,the problem of evolution of slowly,modulated wave train on porous seabed is investigated with the method of multiple scales.For the sea water in the upper region,the classical potential theory is used while the fluid motion in the porous sea bed is describedby Darcy’s law.The equations of the first and second order modulations of wave amplitudeare derived by using matching conditions on the sea bed.The corresponding solutions arefound and seepage pressures are also given at the same time. 相似文献
